    What is the maximum length of a train in your country ?

    In France, the maximum length of a freight train is 750 meters, including the locomotive. The French nework is built with marshalling yards and passing sidings allowing this length. In Europe, this length is not the same everywhere: for instance a train going from Paris to Milano must be cut into two trains when it enters in Italy where the length is 550 m. Since 2012, the length of 850 m is allowed for some routes (Paris - Marseilles). Trials have been running successfully with trains of 1500 m.

    Dragan Djordjevic is right. The maximum train lenght is 750 meters according to AGC.

    How to measure lane change behaviour or lateral shifting of vehicles practically on road?

    I want to calculate the lateral shifting / lane changing behaviour of vehicle in a traffic stream. I want to know about some methods by which practically this distance can be calculated on road?

    thanks for all of your answers

  • Henk Taale added an answer:
    Could you recommend any paper about VDF (volume-delay function) developed with data obtained with use of ITS?

    It would be important for me to get information about any case where data from ITS (Traffic control systems, information systems etc.) were used to develop VDF.

    Can anyone recommend references for KPI of a recycling system?
    Key performance indicators for transport efficiency.

    I think the transport efficiency is independent of the segment (if distribution or reverse logistics). However, an index relating the product output to the return of reusable material in the same period, would be a good indicator

    Can we reduce excess (or excessive) commuting travel by auto?
    Given that the spatial organization of the city is fixed (or worse, increasingly sprawled) what can we do to reduce the VMT needed for commuting? Are there signs that US style patterns will dominate in large cities?
    Alain L'Hostis · Institut Français des Sciences et Technologies des Transports, de l’Aménagement et des Réseaux

    I suggest to use cautiously the concept of excess commuting because of three arguments. There is some excess from one particular point of view, that of the spatial planner, or the urban researcher; there is probably no excess from the point of view of the traveller. In addition excess travel in the literature sometimes refer to trips longer than they could be (King et Mast 1987) and trips done by pure pleasure of the trip itself (Mokhtarian et Salomon 2001). I have no suggestion for an alternative concept but wanted just to warn that this can have several interpretations not directly related to the topic of auto and urban form.

    What are the roles of transportation (planning) in addressing regional inequalities?
    Variations in development of any region are dictates of the available resources and the levels of their development, thus presenting regions as developed, developing, and under-developed regions. The main goal of regional planning as a field of study is to promote regional development.

    @ Ana, thank you for the attached document. I hope to study it and give you feedback soonest
